Theodore Ts'o a54aa76108 ext4: don't leave PageWriteback set after memory failure ... In ext4_bio_write_page(), if the memory allocation for the struct ext4_io_page fails, it returns with the page's PageWriteback flag set. This will end up causing the page not to skip writeback in WB_SYNC_NONE mode, and in WB_SYNC_ALL mode (i.e., on a sync, fsync, or umount) the writeback daemon will get stuck forever on the wait_on_page_writeback() function in write_cache_pages_da(). Or, if journalling is enabled and the file gets deleted, it the journal thread can get stuck in journal_finish_inode_data_buffers() call to filemap_fdatawait(). Another place where things can get hung up is in truncate_inode_pages(), called out of ext4_evict_inode(). Fix this by not setting PageWriteback until after we have successfully allocated the struct ext4_io_page. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>		2011-02-27 16:43:24 -05:00
