* [XFS] kill di_mode checks after xfs_igetChristoph Hellwig2008-04-291-6/+0
| | | | | | | | | | | | | | Unless XFS_IGET_CREATE is passed xfs_iget will return ENOENT if it encounters an inode with di_mode == 0. Remove the duplicated checks in the callers. (the log recovery case is not touched for now) SGI-PV: 976035 SGI-Modid: xfs-linux-melb:xfs-kern:30898a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
* [XFS] Propagate errors from xfs_trans_commit().David Chinner2008-04-181-2/+2
| | | | | | | | | | | | | | | | xfs_trans_commit() can return errors when there are problems in the transaction subsystem. They are indicative that the entire transaction may be incomplete, and hence the error should be propagated as there is a good possibility that there is something fatally wrong in the filesystem. Catch and propagate or warn about commit errors in the places where they are currently ignored.

| | | | | | | | | | | | | | xfs_qm_mount_quotas() returns an error status that is ignored. If we fail to mount quotas, we continue with quota's turned off, which is all handled inside xfs_qm_mount_quotas(). Mark it as void to indicate that errors need not be returned to the callers.

With a little more work we can kill VN_RELE altogether and define IRELE in terms of iput directly.

| | | | | | | | | | | | | | | All flags are added to xfs_mount's m_flag instead. Note that the 32bit inode flag was duplicated in both of them, but only cleared in the mount when it was not nessecary due to the filesystem beeing small enough. Two flags are still required here - one to indicate the mount option setting, and one to indicate if it applies or not.

* [XFS] fix nasty quota hashtable allocation bugEric Sandeen2007-09-051-1/+2
| | | | | | | | | | | | | | | | | | This git mod: 77e4635ae191774526ed695482a151ac986f3806 converted to a "greedy" allocation interface, but for the quota hashtables it switched from allocating XFS_QM_HASHSIZE (nr of elements) xfs_dqhash_t's to allocating only XFS_QM_HASHSIZE *bytes* - quite a lot smaller! Then when we converted hsize "back" to nr of elements (the division line) hsize went to 0. This was leading to oopses when running any quota tests on the Fedora 8 test kernel, but the problem has been there for almost a year.

It's called "set_shrinker()", and it needs Your Help. 1) Don't hide struct shrinker. It contains no magic. 2) Don't allocate "struct shrinker". It's not helpful. 3) Call them "register_shrinker" and "unregister_shrinker". 4) Call the function "shrink" not "shrinker". 5) Reduce the 17 lines of waffly comments to 13, but document it properly.

* [XFS] Quota inode has no parent.David Chinner2007-07-141-2/+1
| | | | | | | | | | | | | | Avoid using a special "zero inode" as the parent of the quota inode as this can confuse the filestreams code into thinking the quota inode has a parent. We do not want the quota inode to follow filestreams allocation rules, so pass a NULL as the parent inode and detect this condition when doing stream associations.

Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.
