ncpfs: fix a braino in OOM handling in ncp_fill_cache()

2016-03-08T03:25:16Z

Failing to allocate an inode for child means that cache for *parent* is incompletely populated. So it's parent directory inode ('dir') that needs NCPI_DIR_CACHE flag removed, *not* the child inode ('inode', which is what we'd failed to allocate in the first place).

wrappers for ->i_mutex access

2016-01-22T23:04:28Z

parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested}, inode_foo(inode) being mutex_foo(&inode->i_mutex). Please, use those for access to ->i_mutex; over the coming cycle ->i_mutex will become rwsem, with ->lookup() done with it held only shared. Signed-off-by: Al Viro

fs/ncpfs/dir.c: remove unnecessary new_valid_dev() check

2015-11-09T23:11:24Z

new_valid_dev() always returns 1, so the !new_valid_dev() check is not needed. Remove it. Signed-off-by: Yaowei Bai Cc: Alexander Viro Cc: Petr Vandrovec Cc: Jan Kara Cc: Jens Axboe Cc: Tejun Heo Cc: Fabian Frederick Cc: David Howells Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

fs: Drop unlikely before IS_ERR(_OR_NULL)

IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there is no need to do that again from its callers. Drop it. Signed-off-by: Viresh Kumar Reviewed-by: Jeff Layton Reviewed-by: David Howells Reviewed-by: Steve French Signed-off-by: Jiri Kosina

ncpfs: get rid of d_validate() nonsense

2015-01-26T04:16:26Z

What we want is to have non-counting references to children in pagecache of parent directory, and avoid picking them after a child has been freed. Fine, so let's just have ->d_prune() clear parent's inode "has directory contents in page cache" flag. That way we don't need ->d_fsdata for storing offsets, so we can use it as a quick and dirty "is it referenced from page cache" flag. Signed-off-by: Al Viro
