* logfs: kill BKLArnd Bergmann2010-08-141-3/+3
| | | | | | | | | | logfs does not need the BKL, so use ->unlocked_ioctl instead of ->ioctl in file operations. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Joern Engel <joern@logfs.org> [ fixed trivial conflict ] Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
* always call inode_change_ok early in ->setattrChristoph Hellwig2010-08-091-4/+4
| | | | | | | | | Make sure we call inode_change_ok before doing any changes in ->setattr, and make sure to call it even if our fs wants to ignore normal UNIX permissions, but use the ATTR_FORCE to skip those.

* remove inode_setattrChristoph Hellwig2010-08-091-7/+11
| | | | | | | | | | | | | | | | | | | Replace inode_setattr with opencoded variants of it in all callers. This moves the remaining call to vmtruncate into the filesystem methods where it can be replaced with the proper truncate sequence. In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.
