ext4: prevent ext4_quota_write() from failing due to ENOSPC In order to prevent quota block tracking to be inaccurate when ext4_quota_write() fails with ENOSPC, we make two changes. The quota file can now use the reserved block (since the quota file is arguably file system metadata), and ext4_quota_write() now uses ext4_should_retry_alloc() to retry the block allocation after a commit has completed and released some blocks for allocation. This fixes failures of xfstests generic/270: Quota error (device vdc): write_blk: dquota write failed Quota error (device vdc): qtree_write_dquot: Error -28 occurred while creating quota Signed-off-by: Theodore Ts'o <tytso@mit.edu>
