mm, fs: introduce mapping_gfp_constraint()

2015-11-07T01:50:42+00:00

There are many places which use mapping_gfp_mask to restrict a more generic gfp mask which would be used for allocations which are not directly related to the page cache but they are performed in the same context. Let's introduce a helper function which makes the restriction explicit and easier to track. This patch doesn't introduce any functional changes.

ntfs: delete unnecessary checks before calling iput()

2015-09-04T23:54:41+00:00

iput() tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

Pull more vfs updates from Al Viro: "Assorted VFS fixes and related cleanups (IMO the most interesting in that part are f_path-related things and Eric's descriptor-related stuff).

mm: do not ignore mapping_gfp_mask in page cache allocation paths

2015-06-25T00:49:44+00:00

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.

fs: cleanup slight list_entry abuse

2015-06-23T22:01:59+00:00

list_entry is just a wrapper for container_of, but it is arguably wrong (and slightly confusing) to use it when the pointed-to struct member is not a struct list_head. Use container_of directly instead. Signed-off-by: Rasmus Villemoes Signed-off-by: Al Viro

fs: Rename file_remove_suid() to file_remove_privs()

2015-06-23T22:01:08+00:00

file_remove_suid() is a misnomer since it removes also file capabilities stored in xattrs and sets S_NOSEC flag. Also should_remove_suid() tells something else than whether file_remove_suid() call is necessary which leads to bugs. Signed-off-by: Jan Kara Signed-off-by: Al Viro
