switch ->create() to umode_t

2012-01-04T03:54:53+00:00

vfs_create() ignores everything outside of 16bit subset of its
mode argument; switching it to umode_t is obviously equivalent
and it's the only caller of the method

switch vfs_mkdir() and ->mkdir() to umode_t

2012-01-04T03:54:53+00:00

vfs_mkdir() gets int, but immediately drops everything that might not
fit into umode_t and that's the only caller of ->mkdir()...

AFS: Use i_generation not i_version for the vnode uniquifier

2011-06-16T15:44:48+00:00

Store the AFS vnode uniquifier in the i_generation field, not the i_version
field of the inode struct.  i_version can then be given the AFS data version
number.

vfs: push dentry_unhash on rename_dir into file systems

2011-05-26T11:26:48+00:00

Only a few file systems need this.  Start by pushing it down into each
rename method (except gfs2 and xfs) so that it can be dealt with on a
per-fs basis.

vfs: push dentry_unhash on rmdir into file systems

2011-05-26T11:26:47+00:00

Only a few file systems need this.  Start by pushing it down into each
fs rmdir method (except gfs2 and xfs) so it can be dealt with on a per-fs
basis.

This does not change behavior for any in-tree file systems.

AFS: Use d_automount() rather than abusing follow_link()

Make AFS use the new d_automount() dentry operation rather than abusing
follow_link() on directories.

fs: rcu-walk aware d_revalidate method

2011-01-07T06:50:29+00:00

Require filesystems be aware of .d_revalidate being called in rcu-walk
mode (nd->flags & LOOKUP_RCU). For now do a simple push down, returning
-ECHILD from all implementations.

fs: dcache reduce branches in lookup path

2011-01-07T06:50:28+00:00

Reduce some branches and memory accesses in dcache lookup by adding dentry
flags to indicate common d_ops are set, rather than having to check them.
This saves a pointer memory access (dentry->d_op) in common path lookup
situations, and saves another pointer load and branch in cases where we
have d_op but not the particular operation.

Patched with:

git grep -E '[.>]([[:space:]])*d_op([[:space:]])*=' | xargs sed -e 's/\([^\t ]*\)->d_op = \(.*\);/d_set_d_op(\1, \2);/' -e 's/\([^\t ]*\)\.d_op = \(.*\);/d_set_d_op(\&\1, \2);/' -i
