* cifs: use posix_unblock_lock instead of locks_delete_blockJeff Layton2013-06-29
| | | | | | | | | | | | | | | | commit 66189be74 (CIFS: Fix VFS lock usage for oplocked files) exported the locks_delete_block symbol. There's already an exported helper function that provides this capability however, so make cifs use that instead and turn locks_delete_block back into a static function. Note that if fl->fl_next == NULL then this lock has already been through locks_delete_block(), so we should be OK to ignore an ENOENT error here and simply not retry the lock.

* Don't pass inode to ->d_hash() and ->d_compare()Linus Torvalds2013-06-29
| | | | | | | | | | | | Instances either don't look at it at all (the majority of cases) or only want it to find the superblock (which can be had as dentry->d_sb). A few cases that want more are actually safe with dentry->d_inode - the only precaution needed is the check that it hadn't been replaced with NULL by rmdir() or by overwriting rename(), which case should be simply treated as cache miss.

* minix: bug widening a binary "not" operationDan Carpenter2013-06-29
| | | | | | | | | | | "chunk_size" is an unsigned int and "pos" is an unsigned long. The "& ~(chunk_size-1)" operation clears the high 32 bits unintentionally. The ALIGN() macro does the correct thing. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

* SELinux: Institute file_path_has_perm()David Howells2013-06-29
| | | | | | | | | | | | | | Create a file_path_has_perm() function that is like path_has_perm() but instead takes a file struct that is the source of both the path and the inode (rather than getting the inode from the dentry in the path). This is then used where appropriate. This will be useful for situations like unionmount where it will be possible to have an apparently-negative dentry (eg. a fallthrough) that is open with the file struct pointing to an inode on the lower fs.
