  "message": "ext4: fix deadlock in ext4_symlink() in ENOSPC conditions\n\next4_symlink() cannot call __page_symlink() with transaction open.\n__page_symlink() calls ext4_write_begin() which can wait for\ntransaction commit if we are running out of space thus causing a\ndeadlock. Also error recovery in ext4_truncate_failed_write() does not\ncount with the transaction being already started (although I\u0027m not\naware of any particular deadlock here).\n\nFix the problem by stopping a transaction before calling\n__page_symlink() (we have to be careful and put inode to orphan list\nso that it gets deleted in case of crash) and starting another one\nafter __page_symlink() returns for addition of symlink into a\ndirectory.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n",
