Previously, 2 members called `initial' and `cachedzone_la' are used for applying caching policy (whether the workgroup is at either end), which are hard to understand, rename them to `backmost' and `headoffset'. Reviewed-by:

For the case of nr_to_read == lookahead_size, it is better to decompress asynchronously as well since no page will be needed immediately. Reviewed-by:

Let's make sure that the one registering a workgroup will also take the primary work lock at first for two reasons: 1) There's no need to introduce such a race window (and consequently overhead) between registering and locking, other tasks could break in by chance, and the race seems unnecessary (no benefit at all); 2) It's better to take the primary work when a workgroup is registered to apply the cache managed policy, for example, if some other tasks break in, it could turn into the in-place decompression rather than use as the cached decompression.

`z_erofs_vle_workgroup' is heavily generated in the decompression, for example, it resets 32 bytes redundantly for 64-bit platforms even through Z_EROFS_VLE_INLINE_PAGEVECS + Z_EROFS_CLUSTER_MAX_PAGES, default 4, pages are stored in `z_erofs_vle_workgroup'. As an another example, `struct mutex' takes 72 bytes for our kirin 64-bit platforms, it's unnecessary to be reseted at first and be initialized each time. Let's avoid filling all `z_erofs_vle_workgroup' with 0 at first since most fields are reinitialized to meaningful values later, and pagevec is no need to initialized at all. Reviewed-by:

There are two minor issues in the current freeze interface: 1) Freeze interfaces have not related with CONFIG_DEBUG_SPINLOCK, therefore fix the incorrect conditions; 2) For SMP platforms, it should also disable preemption before doing atomic_cmpxchg in case that some high priority tasks preempt between atomic_cmpxchg and disable_preempt, then spin on the locked refcount later.

It's better to use atomic_cond_read_relaxed, which is implemented in hardware instructions to monitor a variable changes currently for ARM64, instead of open-coded busy waiting. Reviewed-by:

When the managed cache is enabled, the last reference count of a workgroup must be used for its workstation. Otherwise, it could lead to incorrect (un)freezes in the reclaim path, and it would be harmful. A typical race as follows: Thread 1 (In the reclaim path) Thread 2 workgroup_freeze(grp, 1) refcnt = 1 ... workgroup_unfreeze(grp, 1) refcnt = 1 workgroup_get(grp) refcnt = 2 (x) workgroup_put(grp) refcnt = 1 (x) ...unexpected behaviors * grp is detached but still used, which violates cache-managed freeze constraint.

It's better not to positively BUG_ON the kernel, however developers need a way to locate issues as soon as possible. DBG_BUGON is introduced and it could only crash when EROFS_FS_DEBUG (EROFS developping feature) is on. It is helpful for developers to find and solve bugs quickly by eng builds. Previously, DBG_BUGON is defined as ((void)0) if EROFS_FS_DEBUG is off, but some unused variable warnings as follows could occur: drivers/staging/erofs/unzip_vle.c: In function `init_alway:': drivers/staging/erofs/unzip_vle.c:61:33: warning: unused variable `work' [-Wunused-variable] struct z_erofs_vle_work *const work = ^~~~ Fix it to #define DBG_BUGON(x) ((void)(x)).

`trace_erofs_readpage' was designed for .readpage() interface hook in order to trace the detailed synchronized read rather than the internal implementation `z_erofs_do_read_page' which both .readpage() and .readpages() use. It seems the tracepoint was placed to a wrong place by mistake and it should be moved to the right place. Fixes: 284db12c ("staging: erofs: add trace points for reading zipped data") Reviewed-by:

Merge tag 'iio-for-4.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.21 cycle Along with the headline feature of 5 new drivers, we have the substantial addition of auxilliary sensor support on the lsm6sdx parts for ST. There has also been a good set of staging cleanup in this period with more underway. An ever increasing number of devices supported with just a new ID which is a good sign that at least some manufacturers are continuing to stabilise their interfaces. New device support, * ad7124 - New driver supporting Analog Devices' ad7124-4 and ad7124-8 parts with the inevitable DT binding. * ad7949 - New driver supporting Analog Devices' ad7949, AD7682 and AD7689 ADCs. * rm3100 - New driver supporting PNIs RM3100 magnometer with bindings and vendor prefix. * ti-dac7311 - New driver supporting DAC7311, DAC6311 and DAC5311 TI DACs, with DT bindings. * vcnl5035 - New driver supporting the light sensor part of the VCNL4035, with DT bindings Features, * bindings - Add a generic ADC channel binding as we keep reinventing this wheel. * adc128s052 - Add IDs for additional pin compatible parts. - Add APCI ID seen on E3940 UP squared boards. * ad_sigma_delta - Allow for custom data register overiding default. * kxcjk1013 - Add KIOX0009 ACPI ID as seen on the Acer One 10. * lsm6dsx - Rework leading to... - External sensor support using the built in I2C master. - Initial support for a slave lis2mdl magnetometer. * meson-saradc - Add temperature sensor support and bindings. * st_magn - New ID for lsm9dsl_magn with bindings - New ID for lis3de accelerometer * tpl0102 - Add supprot for IIO_AVAIL_RANGE to report the range available from this device to userspace and in kernel users. Cleanups and minor fixes * tools - Allow outside specification of CFLAGS * ad2s90 - Handle and spi_read error. - Handle spi_setup failure - Drop a pointless assignment. - Prevent a potentail race by moving device registration to after all other setup. - Add missing scale attribute. - Add a sanity check on channel type before trying to read it. * ad2s1210 - Move to modern gpio descriptors. - Drop a gpioin flag which made no sense as far as we can tell. - Add dt table (bindings doc to follow when this is ready for moving out of staging). * ad5933 - Drop camel-case naming of ext_clk_hz. - White space fixes. * ad7150 - Local variable to shorten overly long line. - Alignment and line break fixes. * ad7280a - Handle an error path that was previously ignored. - Use crc8.h to build the crc table replacing custom code. - Avoid unecessary cast. - Power down the device if an error happens in probe - Use devm routines to simplify probe and remove. * ad7606 - Alignment fixes. * ad7780 - This worked as long as by coincidence an uninitialized value was 0. Lets not rely on that. - Ensure gain update is only used with the ad778x chips that actually support it. - Tidy up pattern mask generation. - Read regulator when scale is requested (which should be infrequent) as it might have changed from initialization. * ad7816 - Move to modern gpio descriptors - Don't use a busy_pin for ad7818 as there isn't one. - Ensure RD/WR and CONVST pins are outputs (previously they were brought up as inputs which doesn't seem to make any sense) - DT id table. * adc128s052 - SPDX * adt7316 - Alignment fix. - Fix data reading. When using I2C the driver never actually used the value read. This has been broken a very long time hence no rush to fix it now + the driver is undergoing a lot of cleanup. - Sanity check that the i2c read didn't fail to actually read anything. * dpot-dac - Mark a switch full through with slightly different text so that gcc doesn't warn on it. * gyro-adc - Fix a wrong file in the MAINTAINERS entry and add binding doc to the listed files. * ina2xx - Add some early returns to clarify error paths in switch. * lsm6dsx - MAINTAINERS entry. * max11100 - SPDX * max9611 - SPDX * mcp4131 - use of_device_get_match_data in preference to spi_get_device_id approach. * rcar-adc - SPDX * sc27xx - Add ADC conversion timeout support to avoid possible fault. * ssp_sensors - Don't free managed resources manually. * st-magn - Add a comment to avoid future confusion over when to use -magn postfix (on multi chip in package parts) - Add BDU register for LIS3MDL where it seems to have been missed. * st-sensors - Minor spelling, grammar etc fixes. * tpl0102 - Use a pointer rather than an index of an array to improve conciseness. * tag 'iio-for-4.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (80 commits) Staging: iio: adt7316: Add an extra check for 'ret' equals to 0 Staging: iio: adt7316: Fix i2c data reading, set the data field dt-bindings: iio: adc: Add docs for ad7124 iio: adc: Add ad7124 support dt-bindings: iio: adc: Add common ADCs properties to a separate file iio: ad_sigma_delta: Allow to provide custom data register address staging: iio: ad7816: Add device tree table. iio: imu: st_lsm6dsx: add entry in MAINTAINERS file iio: potentiometer: mcp4131: use of_device_get_match_data() staging: iio: adc: ad7280a: use devm_* APIs staging: iio: adc: ad7280a: power down the device on error in probe dt-bindings: iio: imu: st_lsm6dsx: add support to i2c pullup resistors iio: imu: st_lsm6dsx: add hw FIFO support to i2c controller iio: imu: st_lsm6dsx: add st_lsm6dsx_push_tagged_data routine iio: imu: st_lsm6dsx: add i2c embedded controller support iio: imu: st_lsm6dsx: introduce st_lsm6dsx_sensor_set_enable routine iio: imu: st_lsm6dsx: introduce ST_LSM6DSX_ID_EXT sensor ids iio: imu: st_lsm6dsx: remove static from st_lsm6dsx_set_watermark iio: imu: st_lsm6dsx: reload trimming parameter at bootstrap iio: imu: st_lsm6dsx: introduce locked read/write utility routines ...

As one can see in a typedef at linux/types.h:103, s32 and int32_t are both a 32 bits signed integer. s32 is preferred because it is defined by the kernel maintainers and it prevents portability issues. Changed to meet checkpatch criteria. Signed-off-by:
