Subject: [RFC 00/16] ext4: mballoc/extents: Code cleanup and debug improvements
Date: Sun, 10 May 2020 11:54:40 +0530 [thread overview]
Message-ID: <cover.1589086800.git.riteshh@linux.ibm.com> (raw)
Hello All,
This series does some code refactoring/cleanups and debug logs improvements
around mb_debug() and ext_debug(). These were found when working over
improving mballoc ENOSPC handling in ext4.
These should be small and stright forward patches for reviewing.
Ritesh Harjani (16):
ext4: mballoc: Do print bb_free info even when it is 0
ext4: mballoc: Refactor ext4_mb_show_ac()
ext4: mballoc: Add more mb_debug() msgs
ext4: mballoc: Correct the mb_debug() format specifier for pa_len var
ext4: mballoc: Fix few other format specifier in mb_debug()
ext4: mballoc: Simplify error handling in ext4_init_mballoc()
ext4: mballoc: Make ext4_mb_use_preallocated() return type as bool
ext4: mballoc: Refactor code inside DOUBLE_CHECK into separate function
ext4: mballoc: Fix possible NULL ptr & remove BUG_ONs from DOUBLE_CHECK
ext4: balloc: Use task_pid_nr() helper
ext4: Use BIT() macro for BH_** state bits
ext4: Improve ext_debug() msg in case of block allocation failure
ext4: Replace EXT_DEBUG with __maybe_unused in ext4_ext_handle_unwritten_extents()
ext4: mballoc: Make mb_debug() implementation to use pr_debug()
ext4: Make ext_debug() implementation to use pr_debug()
ext4: Add process name and pid in ext4_msg()
