Don't pass inode to ->d_hash() and ->d_compare() · da53be12

由 Linus Torvalds 提交于 5月 21, 2013

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" operation · 642b704c

由 Dan Carpenter 提交于 6月 19, 2013

"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

adding to it is fsnotify_fasync() itself and it's never
called for fanotify files while they are opened.

SELinux: Institute file_path_has_perm() · 13f8e981

由 David Howells 提交于 6月 13, 2013

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.
