2021-04-12T13:04:29+00:00

Use the fileattr API to let the VFS handle locking, permission checking and
conversion.

fs: make helpers idmap mount aware

2021-01-24T13:27:20+00:00

Extend some inode methods with an additional user namespace argument. A
filesystem that is aware of idmapped mounts will receive the user
namespace the mount has been marked with. This can be used for
additional permission checking and also to enable filesystems to
translate between uids and gids if they need to. We have implemented all
relevant helpers in earlier patches.

As requested we simply extend the exisiting inode method instead of
introducing new ones. This is a little more code churn but it's mostly
mechanical and doesnt't leave us with additional inode methods.

gfs2: Minor gfs2_lookup_by_inum cleanup

2020-06-05T18:19:21+00:00

Use a zero no_formal_ino instead of a NULL pointer to indicate that any inode
generation number will qualify: a valid inode never has a zero no_formal_ino.

gfs2: Fix an incorrect gfs2_assert()

2019-03-06T14:00:43+00:00

When updating the inode information after a change in allocation,
convert the change into the same units as the inode's i_blocks count
before comparing it in an assertion.

Also, change the comparison so that it is still possible to set i_blocks
to zero by adding -i_blocks, something that was previously only possible
because of the difference in units.

gfs2: Clean up gfs2_is_{ordered,writeback}

2018-12-11T16:50:35+00:00

The gfs2_is_ordered and gfs2_is_writeback checks are weird in that they
implicitly check for !gfs2_is_jdata.  This makes understanding how to
use those functions correctly a challenge.  Clean this up by making
gfs2_is_ordered and gfs2_is_writeback take a super block instead of an
inode and by removing the implicit !gfs2_is_jdata checks.  Update the
callers accordingly.
