fs: convert fs shrinkers to new scan/count API

2013-09-10T22:56:31+00:00

Convert the filesystem shrinkers to use the new API, and standardise some
of the behaviours of the shrinkers at the same time.  For example,
nr_to_scan means the number of objects to scan, not the number of objects
to free.

I refactored the CIFS idmap shrinker a little - it really needs to be
broken up into a shrinker per tree and keep an item count with the tree
root so that we don't need to walk the tree every time the shrinker needs
to count the number of objects in the tree (i.e.  all the time under
memory pressure).

[glommer@openvz.org: fixes for ext4, ubifs, nfs, cifs and glock. Fixes are needed mainly due to new code merged in the tree]

nfsd4: fix leak of inode reference on delegation failure

2013-08-30T21:30:52+00:00

This fixes a regression from 68a3396178e6688ad7367202cdf0af8ed03c8727
"nfsd4: shut down more of delegation earlier".

After that commit, nfs4_set_delegation() failures result in
nfs4_put_delegation being called, but nfs4_put_delegation doesn't free
the nfs4_file that has already been set by alloc_init_deleg().

This can result in an oops on later unmounting the exported filesystem.

Note also delaying the fi_had_conflict check we're able to return a
better error (hence give 4.1 clients a better idea why the delegation
failed; though note CONFLICT isn't an exact match here, as that's
supposed to indicate a current conflict, but all we know here is that
there was one recently).

Revert "nfsd: nfs4_file_get_access: need to be more careful with O_RDWR"

2013-08-30T21:30:45+00:00

This reverts commit df66e75395c839c3a373bae897dbb1248f741b45.

nfsd4_lock can get a read-only or write-only reference when only a
read-write open is available.  This is normal.
