BUG_ON() Conversion in fs/sysfs/

2006-03-31T23:18:38+00:00

this changes if() BUG(); constructs to BUG_ON() which is
cleaner, contains unlikely() and can better optimized away.

[PATCH] sysfs: sysfs_remove_dir() needs to invalidate the dentry

2006-03-20T21:42:57+00:00

When calling sysfs_remove_dir() don't allow any further sysfs functions
to work for this kobject anymore.  This fixes a nasty USB cdc-acm oops
on disconnect.

Many thanks to Bob Copeland and Paul Fulghum for taking the time to
track this down.

[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem

2006-01-09T23:59:24+00:00

This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.

[PATCH] Fix oops in sysfs_hash_and_remove_file()

2005-08-27T02:37:13+00:00

The problem arises if an entity in sysfs is created and removed without
ever having been made completely visible.  In SCSI this is triggered by
removing a device while it's initialising.

The problem appears to be that because it was never made visible in sysfs,
the sysfs dentry has a null d_inode which oopses when a reference is made
to it.  The solution is simply to check d_inode and assume the object was
never made visible (and thus doesn't need deleting) if it's NULL.

(akpm: possibly a stopgap for 2.6.13 scsi problems.  May not be the
long-term fix)

[PATCH] sysfs: fix sysfs_setattr

2005-07-29T20:12:49+00:00

o sysfs_dirent's s_mode field should also be updated in sysfs_setattr(), else
  there could be inconsistency in the two fields. s_mode is used while
  ->readdir so as not to bring in the inode to cache.

[PATCH] remove duplicate get_dentry functions in various places

2005-06-23T16:45:20+00:00

Various filesystem drivers have grown a get_dentry() function that's a
duplicate of lookup_one_len, except that it doesn't take a maximum length
argument and doesn't check for \0 or / in the passed in filename.

Switch all these places to use lookup_one_len.

[PATCH] sysfs-iattr: set inode attributes

2005-06-20T22:15:37+00:00

o Following patch sets the attributes for newly allocated inodes for sysfs
  objects. If the object has non-default attributes, inode attributes are
  set as saved in sysfs_dirent->s_iattr, pointer to struct iattr.

[PATCH] sysfs-iattr: add sysfs_setattr

2005-06-20T22:15:37+00:00

o This adds ->i_op->setattr VFS method for sysfs inodes. The changed
  attribues are saved in the persistent sysfs_dirent structure as a pointer
  to struct iattr. The struct iattr is allocated only for those sysfs_dirent's
  for which default attributes are getting changed. Thanks to Jon Smirl for
  this suggestion.
