Stop using legacy PM ops and switch using dev_pm_ops. Along with it #ifdef CONFIG_PM are removed and __maybe_unused and pm_ptr() used instead. Coding style recommends (at chapter Conditional Compilation) to avoid using preprocessor conditional and use __maybe_unused instead. Acked-by:

Since commit 31f6bd7f ("serial: Store character timing information to uart_port"), per frame timing information is available on uart_port. Uart port's timeout can be derived from frame_time by multiplying with fifosize. Most callers of uart_poll_timeout are not made under port's lock. To be on the safe side, make sure frame_time is only accessed once. As fifo_size is effectively a constant, it shouldn't cause any issues. Signed-off-by:

As a follow-up to the commit 4173f018 (tty/vt: consolemap: rename and document struct uni_pagedir), rename also the members of struct vc_data. I.e. pagedir -> pagedict. And while touching all the places, remove also the unnecessary vc_ prefix. Suggested-by:

The function uses too vague variable names like i, j, k for iterators, p, q, p1, p2 for pointers etc. Rename all these, so that it is clear what is going on: - dict: for dictionaries. - d, r, g: for dir, row, glyph iterators -- these are unsigned now. - dir, row: for directory and row pointers. - glyph: for the glyph. - and so on... This is a lot of shuffling, but the result pays off, IMO. Reviewed-by:

We capture a NULL pointer issue when resizing a corrupt ext4 image which is freshly clear resize_inode feature (not run e2fsck). It could be simply reproduced by following steps. The problem is because of the resize_inode feature was cleared, and it will convert the filesystem to meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was not reduced to zero, so could we mistakenly call reserve_backup_gdb() and passing an uninitialized resize_inode to it when adding new group descriptors. mkfs.ext4 /dev/sda 3G tune2fs -O ^resize_inode /dev/sda #forget to run requested e2fsck mount /dev/sda /mnt resize2fs /dev/sda 8G ======== BUG: kernel NULL pointer dereference, address: 0000000000000028 CPU: 19 PID: 3243 Comm: resize2fs Not tainted 5.18.0-rc7-00001-gfde086c5ebfd #748 ...

ext4_mb_normalize_request() can move logical start of allocated blocks to reduce fragmentation and better utilize preallocation. However logical block requested as a start of allocation (ac->ac_o_ex.fe_logical) should always be covered by allocated blocks so we should check that by modifying and to or in the assertion.

Since ext4 was converted to the new mount API, the test_dummy_encryption mount option isn't being handled entirely correctly, because the needed fscrypt_set_test_dummy_encryption() helper function combines parsing/checking/applying into one function. That doesn't work well with the new mount API, which split these into separate steps. This was sort of okay anyway, due to the parsing logic that was copied from fscrypt_set_test_dummy_encryption() into ext4_parse_param(), combined with an additional check in ext4_check_test_dummy_encryption(). However, these overlooked the case of changing the value of test_dummy_encryption on remount, which isn't allowed but ext4 wasn't detecting until ext4_apply_options() when it's too late to fail. Another bug is that if test_dummy_encryption was specified multiple times with an argument, memory was leaked. Fix this up properly by using the new helper functions that allow splitting up the parse/check/apply steps for test_dummy_encryption.
