2015-06-24mm: do not ignore mapping_gfp_mask in page cache allocation pathsMichal Hocko2-2/+3
page_cache_read, do_generic_file_read, __generic_file_splice_read and __ntfs_grab_cache_pages currently ignore mapping_gfp_mask when calling add_to_page_cache_lru which might cause recursion into fs down in the direct reclaim path if the mapping really relies on GFP_NOFS semantic. This doesn't seem to be the case now because page_cache_read (page fault path) doesn't seem to suffer from the reclaim recursion issues and do_generic_file_read and __generic_file_splice_read also shouldn't be called under fs locks which would deadlock in the reclaim path. Anyway it is better to obey mapping gfp mask and prevent from later breakage.

2015-06-24procfs: treat parked tasks as sleeping for task stateChris Metcalf1-0/+8
Allowing watchdog threads to be parked means that we now have the opportunity of actually seeing persistent parked threads in the output of /proc/<pid>/stat and /proc/<pid>/status. The existing code reported such threads as "Running", which is kind-of true if you think of the case where we park them as part of taking cpus offline. But if we allow parking them indefinitely, "Running" is pretty misleading, so we report them as "Sleeping" instead. We could simply report them with a new string, "Parked", but it feels like it's a bit risky for userspace to see unexpected new values; the output is already documented in Documentation/filesystems/proc.txt, and it seems like a mistake to change that lightly. The scheduler does report parked tasks with a "P" in debugging output from sched_show_task() or dump_cpu_task(), but that's a different API. Similarly, the trace_ctxwake_* routines report a "P" for parked tasks, but again, different API. This change seemed slightly cleaner than updating the task_state_array to have additional rows. TASK_DEAD should be subsumed by the exit_state bits; TASK_WAKEKILL is just a modifier; and TASK_WAKING can very reasonably be reported as "Running" (as it is now). Only TASK_PARKED shows up with unreasonable output here.

2015-06-24ocfs2: remove BUG_ON(!empty_extent) in __ocfs2_rotate_tree_left()Xue jiufei1-1/+2
ocfs2_rotate_tree_left() calls __ocfs2_rotate_tree_left() for left rotation while non-rightmost path containing an empty extent in the leaf block. __ocfs2_rotate_tree_left() returns -EAGAIN if right subtree having an empty extent and pass the empty_extent_path to caller. The caller ocfs2_rotate_tree_left() will restart rotation from the returned path. It will trigger the BUG_ON(!ocfs2_is_empty_extent) when the et on disk is as follows: eb0 is the leaf block of path(say path_a) passed to ocfs2_rotate_tree_left, which has an empty rec[0]. eb1 is the leaf block of path(say path_b) that just right to path_a, which has no empty record. eb2 is the leaf block of path(say path_c) that just right to path_b, which has an empty rec[0]. And path_c is also the rightmost path. Now we want to remove the empty rec[0] in eb0: ocfs2_rotate_tree_left: -> call __ocfs2_rotate_tree_left with path_a as its input *path* -> call ocfs2_rotate_subtree_left with path_a as its input *left_path* and path_b as its input *right_path*. it will move rec[0] in eb1 to eb0, and rec[0] in eb0 is not empty now. -> continue to call ocfs2_rotate_subtree_left with path_b as its input *left_path* and path_c as its input *right_path*, and return -EAGAIN because eb2 has an empty rec[0] -> call __ocfs2_rotate_tree_left with path_c as it input, rotate all records in eb2 to left and return 0. -> call __ocfs2_rotate_tree_left with path_a as its input, and triggers the BUG_ON(!ocfs2_is_empty_extent) as the rec[0] in eb0 is not empty. So the BUG_ON() should be removed and return 0 if rec[0] is no longer an empty extent.

2015-06-19seqcount: Rename write_seqcount_barrier()Peter Zijlstra1-8/+8
I'll shortly be introducing another seqcount primitive that's useful to provide ordering semantics and would like to use the write_seqcount_barrier() name for that. Seeing how there's only one user of the current primitive, lets rename it to invalidate, as that appears what its doing. While there, employ lockdep_assert_held() instead of assert_spin_locked() to not generate debug code for regular kernels.

2015-06-11f2fs: do not trim preallocated blocks when truncating after i_sizeChao Yu1-4/+4
When we perform generic/092 in xfstests, output is like below: XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) 0: [0..10239]: data 0: [0..10239]: data -1: [10240..20479]: unwritten +1: [10240..14335]: unwritten This is because with this testcase, we redefine the regulation for truncate in perallocated space past i_size as below: "There was some confused about what the fs was supposed to do when you truncate at i_size with preallocated space past i_size. We decided on the following things. 1) truncate(i_size) will trim all blocks past i_size. 2) truncate(x) where x > i_size will not trim all blocks past i_size. " This method is used in xfs, and then ext4/btrfs will follow the rule. This patch fixes to follow the new rule for f2fs.

2015-06-02vfs: read file_handle only once in handle_to_pathSasha Levin1-2/+3
We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again.

2015-06-02f2fs: support FALLOC_FL_INSERT_RANGEChao Yu1-2/+100
FALLOC_FL_INSERT_RANGE flag for ->fallocate was introduced in commit dd46c787788d ("fs: Add support FALLOC_FL_INSERT_RANGE for fallocate"). The effect of FALLOC_FL_INSERT_RANGE command is the opposite of FALLOC_FL_COLLAPSE_RANGE, if this command was performed, all data from offset to EOF in our file will be shifted to right as given length, and then range [offset, offset + length] becomes a hole. This command is useful for our user who wants to add some data in the middle of the file, for example: video/music editor will insert a keyframe in specified position of media file, with this command we can easily create a hole for inserting without removing original data. This patch introduces f2fs_insert_range() to support FALLOC_FL_INSERT_RANGE.
