Add device table support for the LR214WF card. The driver will say it's a FlyTV, simply because the name strings are stored with the card design data, not the device ID data. Signed-off-by:

The extra race-with-truncate-then-retry logic around ext3_get_block_handle(), which was inherited from ext2, becomes unecessary for ext3, since we have already obtained the ei->truncate_sem in ext3_get_block_handle() before calling ext3_alloc_branch(). The ei->truncate_sem is already there to block concurrent truncate and block allocation on the same inode. So the inode's indirect addressing tree won't be changed after we grab that semaphore. We could, after get the semaphore, re-verify the branch is up-to-date or not. If it has been changed, then get the updated branch. If we still need block allocation, we will have a safe version of the branch to work with in the ext3_find_goal()/ext3_splice_branch(). The code becomes more readable after remove those retry logic. The patch also clean up some gotos in ext3_get_block_handle() to make it more readable. Signed-off-by:

Since we only access reiserfs_key ->u.k_offset_v2 guts in four helper functions, we are free to sanitize those, as long as - layout of the structure is unchanged (it's on-disk object) - behaviour of these helpers is same as before. Patch kills the mess with endianness-dependent bitfields and replaces them with a single __le64. Helpers are switched to straightforward shift/and/or. Benefits: - exact same definitions for little- and big-endian architectures; no ifdefs in sight. - generate the same code on little-endian and improved on big-endian. - doesn't rely on lousy bitfields handling in gcc codegenerator. - happens to be standard C (unsigned long long is not a valid type for a bitfield; it's a gccism and not well-implemented one, at that).

comp_short_keys() massaged into sane form, which kills the last place where pointer to in_core_key (or any object containing such) would be cast to or from something else. At that point we are free to change layout of in_core_key - nothing depends on it anymore. So we drop the mess with union in there and simply use (unconditional) __u64 k_offset and __u8 k_type instead; places using in_core_key switched to those. That gives _far_ better code than current mess - on all platforms. Signed-off-by:

little-endian objects annotated as such; again, obviously no changes of resulting code, we only replace __u16 with __le16, etc. in relevant places. Signed-off-by:

struct reiserfs_key cloned; (currently) identical struct in_core_key added. Places that expect host-endian data in reiserfs_key switched to in_core_key. Basically, we get annotation of reiserfs_key users and keep the resulting tree obviously equivalent to original. Signed-off-by:

For tree mount maps, a call to chdir or chroot, to a directory above the moint point directories at a certain time during the expire results in the expire incorrectly thinking the tree is not busy. This patch adds a check to see if the filesystem above the tree mount points is busy and also locks the filesystem during the tree mount expire to prevent the race. Signed-off-by:

This patch fixes the leak of sb->s_fs_info in both the HFS and HFS+ modules. In addition to this, it fixes an oops happening when trying to mount a non-hfsplus filesystem using hfsplus. This patch is from Roman Zippel, based off patches sent by myself. Signed-off-by:

This patch optimizes io_submit_one to call aio_run_iocb() directly if ctx->run_list is empty. When the list is empty, the operation of adding to the list, then call to __aio_run_iocbs() is unnecessary because these operations are done in one atomic step. ctx->run_list always has only one element in this case. This optimization speeds up industry standard db transaction processing benchmark by 0.2%. Signed-off-by:

Since the tail pointer in aio_ring structure never wrap ring size more than once, so a simple compare is sufficient to wrap the index around. This avoid a more expensive mod operation. Signed-off-by:

This patch removes superfluous kiocb member initialization in the AIO allocation and deallocation path. For example, in really_put_req(), right before kiocb is returned to slab, 5 variables are reset to NULL. The same variables will be initialized at the kiocb allocation time, so why bother reset them knowing that they will be set to valid data at alloc time? Another example: ki_retry is initialized in __aio_get_req, but is initialized again in io_submit_one. Signed-off-by:

I've noticed that, starting from linux-2.6.12-rc1, in the top Makefile the "cmd_tags" variable has been changed in a way incompatible with *emacs ctags. Since the "--extra" option exists only in "exuberant ctags", it should be included in the CTAGSF shell variable. Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by:

Convert most of the current code that uses _NSIG directly to instead use valid_signal(). This avoids gcc -W warnings and off-by-one errors. Signed-off-by:

Jesper Juhl authored
This patch adds a new function valid_signal() that tests if its argument is a valid signal number. The reasons for adding this new function are: - some code currently testing _NSIG directly has off-by-one errors. Using this function instead avoids such errors. - some code currently tests unsigned signal numbers for <0 which is pointless and generates warnings when building with gcc -W. Using this function instead avoids such warnings. I considered various places to add this function but eventually settled on include/linux/signal.h as the most logical place for it. If there's some reason this is a bad choice then please let me know (hints as to a better location are then welcome of course). Signed-off-by:

Enable interrupts for a BT interface. There is a specific register that needs to be set up to enable interrupts that also must be modified to clear the irq. Also, don't reset the BMC on a BT interface. That's probably not a good idea as the BMC may be performing other important functions and a reset should only be a last resort. Also, that register is also used to enable/disable interrupts to the BT; modifying it may screw up the interrupts. Signed-off-by:

There were still a few comments left refering to verify_area, and two functions, verify_area_skas & verify_area_tt that just wrap corresponding access_ok_skas & access_ok_tt functions, just like verify_area does for access_ok - deprecate those. There was also a few places that still used verify_area in commented-out code, fix those up to use access_ok. After applying this one there should not be anything left but finally removing verify_area completely, which will happen after a kernel release or two. Signed-off-by:

When allocating a new VC with vgacon_init(), the font is shared across all the VGA consoles. However, the font mask was always set to the default value of zero in visual_init(), even if we were using 512 character fonts at the time. Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the console driver thinks it's already in 512 character mode. This means that to *fix* it, you'd actually have to take the console out of 512 character mode and then set it back. The attached sets vc_hi_font_mask in vgacon_init() for any new consoles opened if the vgacon driver is already in 512 character mode, solving this. This bug goes back to 2.4.18 at least, probably earlier. Signed-off-by:
