Add standard interfaces for alarm/update irqs enabling. Drivers are no more required to implement equivalent ioctl code as rtc-dev will provide it. UIE emulation should now be handled correctly and will work even for those RTC drivers who cannot be configured to do both UIE and AIE. Signed-off-by:

With the write_begin/write_end aops, page_symlink was broken because it could no longer pass a GFP_NOFS type mask into the point where the allocations happened. They are done in write_begin, which would always assume that the filesystem can be entered from reclaim. This bug could cause filesystem deadlocks. The funny thing with having a gfp_t mask there is that it doesn't really allow the caller to arbitrarily tinker with the context in which it can be called. It couldn't ever be GFP_ATOMIC, for example, because it needs to take the page lock. The only thing any callers care about is __GFP_FS anyway, so turn that into a single flag. Add a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on this flag in their write_begin function. Change __grab_cache_page to accept a nofs argument as well, to honour that flag (while we're there, change the name to grab_cache_page_write_begin which is more instructive and does away with random leading underscores). This is really a more flexible way to go in the end anyway -- if a filesystem happens to want any extra allocations aside from the pagecache ones in ints write_begin function, it may now use GFP_KERNEL (rather than GFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a random example).

The function viafb_cursor() uses 2 stack-variables of CURSOR_SIZE bits; CURSOR_SIZE is defined as (8 * 1024). Using up twice 1k on stack is too much for 4k-stack (though it works with 8k-stacks). Make those two variables kzalloc'ed to preserve stack space. Also merge the whole lot of local struct's in viafb_ioctl into a union so the stack usage gets minimized here as well. (struct's are only accessed in their indicidual IOCTL case) This second part is only compile-tested as I know of no userspace app using the IOCTLs. Signed-off-by:

As suggested by Andreas Dilger, introduce a bgl_lock_ptr() helper in <linux/blockgroup_lock.h> and add separate sb_bgl_lock() helpers to filesystem specific header files to break the hidden dependency to struct ext[234]_sb_info. Also, while at it, convert the macros to static inlines to try make up for all the times I broke Andrew Morton's tree. Acked-by:

Problem: ordering between the rules on exit chain is currently lost; all watch and inode rules are listed after everything else _and_ exit,never on one kind doesn't stop exit,always on another from being matched. Solution: assign priorities to rules, keep track of the current highest-priority matching rule and its result (always/never). Signed-off-by:
