2013-06-29Don't pass inode to ->d_hash() and ->d_compare()Linus Torvalds23-165/+108
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.

2013-06-29minix: bug widening a binary "not" operationDan Carpenter1-1/+1
"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.

... especially since there's no way to get that sucker on the list fsnotify_fasync() works with - the only thing adding to it is fsnotify_fasync() itself and it's never called for fanotify files while they are opened. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

the only remaining caller (in ncpfs) is guaranteed to return 0 - we only hit it if we'd just checked that there's no dentry with such name. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2013-06-29SELinux: Institute file_path_has_perm()David Howells1-6/+18
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.
