hpfs: switch to ->iterate_shared()

2016-05-12T23:47:13+00:00

NOTE: the only reason we can do that without ->i_rdir_offs races is that hpfs_lock() serializes everything in there anyway. It's not that hard to get rid of, but not as part of this series... Signed-off-by: Al Viro

hpfs: handle allocation failures in hpfs_add_pos()

2016-05-12T23:35:57+00:00

pr_err() is nice, but we'd better propagate the error to caller and not proceed to violate the invariants (namely, "every file with f_pos tied to directory block should have its address visible in per-inode array"). Signed-off-by: Al Viro

wrappers for ->i_mutex access

2016-01-22T23:04:28+00:00

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/hpfs: increase pr_warn level

2014-06-06T23:08:10+00:00

This patch applies a suggestion by Mikulas Patocka asking to increase all pr_warn without commented ones to pr_err Signed-off-by: Fabian Frederick Cc: Mikulas Patocka Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

fs/hpfs: use pr_fmt for logging

2014-06-06T23:08:10+00:00

Also remove redundant level names (warning:...) Signed-off-by: Fabian Frederick Cc: Mikulas Patocka Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

fs/hpfs: convert printk to pr_foo()

2014-06-06T23:08:10+00:00

No level printk in hptfs_error converted to pr_err (others to pr_warn or pr_info) This patch also fixes if/then/else checkpatch warnings Signed-off-by: Fabian Frederick Cc: Mikulas Patocka Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

hpfs: deadlock and race in directory lseek()

2013-05-31T19:17:43+00:00

For one thing, there's an ABBA deadlock on hpfs fs-wide lock and i_mutex in hpfs_dir_lseek() - there's a lot of methods that grab the former with the caller already holding the latter, so it must take i_mutex first. For another, locking the damn thing, carefully validating the offset, then dropping locks and assigning the offset is obviously racy. Moreover, we _must_ do hpfs_add_pos(), or the machinery in dnode.c won't modify the sucker on B-tree surgeries. Signed-off-by: Al Viro
