VFS: normal filesystems (and lustre): d_inode() annotations

2015-04-15T19:06:57+00:00

that's the bulk of filesystem drivers dealing with inodes of their own

coda: Cache permisions in struct coda_inode_info in a kuid_t.

2013-02-13T14:00:54+00:00

- Change c_uid in struct coda_indoe_info from a vuid_t to a kuid_t.
- Initialize c_uid to GLOBAL_ROOT_UID instead of 0.
- Use uid_eq to compare cached kuids.

dcache_lock no longer protects anything. remove it.

fs: dcache scale subdirs

2011-01-07T06:50:21+00:00

Protect d_subdirs and d_child with d_lock, except in filesystems that aren't
using dcache_lock for these anyway (eg. using i_mutex).

Note: if we change the locking rule in future so that ->d_child protection is
provided only with ->d_parent->d_lock, it may allow us to reduce some locking.
But it would be an exception to an otherwise regular locking scheme, so we'd
have to see some good results. Probably not worthwhile.

Coda: add spin lock to protect accesses to struct coda_inode_info.

2010-10-25T15:02:40+00:00

We mostly need it to protect cached user permissions. The c_flags field
is advisory, reading the wrong value is harmless and in the worst case
we hit a slow path where we have to make an extra upcall to the
userspace cache manager when revalidating a dentry or inode.

CRED: Wrap task credential accesses in the Coda filesystem

2008-11-13T23:38:48+00:00

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.

Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

Change some task->e?[ug]id to task_e?[ug]id().  In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be
addressed by later patches.
