925c86a1 - fs: add CONFIG_BUFFER_HEAD

Tue, 01 Aug 2023 17:22:01 +0000

fs: add CONFIG_BUFFER_HEADAdd a new config option that controls building the buffer_head code, andselect it from all file systems and stacking drivers that need it.For the block device nodes and alternative iomap based buffered I/O pathis provided when buffer_head support is not enabled, and iomap needs aa small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not callinto the buffer_head code when it doesn't exist.Otherwise this is just Kconfig and ifdef changes.Signed-off-by: Christoph Hellwig Reviewed-by: Luis Chamberlain Reviewed-by: Johannes Thumshirn Link: https://lore.kernel.org/r/20230801172201.1923299-7-hch@lst.deSigned-off-by: Jens Axboe List of files: /linux-6.15/fs/ufs/Kconfig

b7e17a10 - fs/ufs: remove depends on CONFIG_EXPERIMENTAL

Thu, 17 Jan 2013 02:54:15 +0000

fs/ufs: remove depends on CONFIG_EXPERIMENTALThe CONFIG_EXPERIMENTAL config item has not carried much meaning for awhile now and is almost always enabled by default. As agreed during theLinux kernel summit, remove it from any "depends on" lines in Kconfigs.CC: Evgeniy Dushistov Cc: Al Viro Signed-off-by: Kees Cook Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/fs/ufs/Kconfig

788257d6 - ufs: remove the BKL

Mon, 24 Jan 2011 09:14:12 +0000

ufs: remove the BKLThis introduces a new per-superblock mutex in UFS to replacethe big kernel lock. I have been careful to avoid nestedcalls to lock_ufs and to get the lock order right withrespect to other mutexes, in particular lock_super.I did not make any attempt to prove that the big kernellock is not needed in a particular place in the code,which is very possible.The mutex has a significant performance impact, so it is onlyused on SMP or PREEMPT configurations.As Nick Piggin noticed, any allocation inside of the lockmay end up deadlocking when we get to ufs_getfrag_blockin the reclaim task, so we now use GFP_NOFS.Signed-off-by: Arnd Bergmann Tested-by: Nick Bowler Cc: Evgeniy Dushistov Cc: Nick Piggin List of files: /linux-6.15/fs/ufs/Kconfig

6de5bd12 - BKL: introduce CONFIG_BKL.

Sat, 11 Sep 2010 16:00:57 +0000

BKL: introduce CONFIG_BKL.With all the patches we have queued in the BKL removal tree, only afew dozen modules are left that actually rely on the BKL, and eventhere are lots of low-hanging fruit. We need to decide what to doabout them, this patch illustrates one of the options:Every user of the BKL is marked as 'depends on BKL' in Kconfig,and the CONFIG_BKL becomes a user-visible option. If it getsdisabled, no BKL using module can be built any more and the BKLcode itself is compiled out.The one exception is file locking, which is practically alwaysenabled and does a 'select BKL' instead. This effectively forcesCONFIG_BKL to be enabled until we have solved the fs/lockdmess and can apply the patch that removes the BKL from fs/locks.c.Signed-off-by: Arnd Bergmann List of files: /linux-6.15/fs/ufs/Kconfig
