Matthew Wilcox (Oracle) 38ed8ab317 quota: Prevent memory allocation recursion while holding dq_lock ... [ Upstream commit 537e11cdc7 ] As described in commit 02117b8ae9 ("f2fs: Set GF_NOFS in read_cache_page_gfp while doing f2fs_quota_read"), we must not enter filesystem reclaim while holding the dq_lock. Prevent this more generally by using memalloc_nofs_save() while holding the lock.
