I noticed that list.h init functions were evaluating macro arguments multiple times and thought it might be nice to protect the unsuspecting caller. Converting the macros to inline functions seems to reduce code size, too.

When one module exports a function symbol and another module uses that symbol then kallsyms shows the symbol twice. Once from the consumer with a type of 'U' and once from the provider with a type of 't' or 'T'. On most architectures, both entries have the same address so it does not matter which one is returned by kallsyms_lookup_name(). But on architectures with function descriptors, the 'U' entry points to the descriptor, not to the code body, which is not what we want. IA64 # grep -w qla2x00_remove_one /proc/kallsyms a000000208c25ef8 U qla2x00_remove_one [qla2300] <= descriptor a000000208bf44c0 t qla2x00_remove_one [qla2xxx] <= function body Tell kallsyms_lookup_name() to ignore type U entries in modules.

This patch adds missing initialization sequence, necessary to get the "Macintosh" version of AEC6280 cards to work in Linux. Without this patch, the driver hangs for several minutes trying to initialize the card and the kernel is left in an unstable state. This patch has been tested fine on ppc and i386. Signed-off-by:

When two function-return probes are inserted on kfree()[1] and the second on say, sys_link()[2], and later [2] is unregistered, we have a deadlock as kfree is called with the kretprobe_lock held and the function-return probe on kfree will also try to grab the same lock. However, we can move the kfree() during unregistration to outside the spinlock as we are sure that no instances from the free list will be used after synchronized_sched() returns during the unregistration process. Thanks to Masami Hiramatsu for spotting this. Signed-off-by:

mdu_array_info_t->size is 'int', which isn't big enough for the size (in KB of each component in) some arrays. So rather than a random overflow, set size to -1 when it cannot be set correctly. To update aspect on an array, userspace will sometimes: get_array_info change one field set_array_info in this case, we don't want the '-1' in 'size' to change to size, or look like a size change at all. So test for that in update_array_info. Signed-off-by:

Edits to the driver-model documentation for grammar, clarity and content. These docs haven't been updated in years, and some of the technical content and discussion has become stale; this patch updates these. In addition, some of the language is awkward. Fix this.

This is a fix to the device-mapper-log-bitset-fix-endian patch that switched to ext2_* versions of the set and clear bit functions. The find_next_zero_bit function also has to be the ext2 one. Otherwise the mirror target tries to recover non-existent regions beyond the end of device. Signed-off-by:

NeilBrown authored
While a read-only array doesn't not really need a bitmap, we should not remove the bitmap when switching an array to read-only because a/ There is no code to re-add the bitmap which switching to read-write, b/ There is insufficient locking - the bitmap could be accessed while it is being removed.

NeilBrown authored
As 'array_size' is a 'sector_t', it may overflow inappropriately when shifted 10 bits. So We should cast it to a loff_t first. There are two places with this problem, but the second (in update_raid_disks) isn't needed so just remove it: The only personality that handles ->reshape currently is raid1, and it doesn't change the size of the array. When added for raid5/6, reshape again won't change the size of the array, at least not straight away. This code might be need for reshaping 'linear' but linear->shape, if implemented, should probably do the i_size_write itself. Signed-off-by:

Most of the 64 bit architectures will zero extend the first argument to compat_sys_{openat,newfstatat,futimesat} which will fail if the 32 bit syscall was passed AT_FDCWD (which is a small negative number). Declare the first argument to be an unsigned int which will force the correct sign extension when the internal functions are called in each case. Also, do some small white space cleanups in fs/compat.c. Signed-off-by:Stephen Rothwell <sfr@canb.auug.org.au> Acked-by:
