reada is using -1 instead of the -ENOMEM defined macro to specify that a buffer allocation failed. Since the error number is propagated, the caller will get a -EPERM which is the wrong error condition. Also, updating the caller to return the exact value from reada_add_block.

Below variables are defined per compress type. - struct list_head comp_idle_workspace[BTRFS_COMPRESS_TYPES] - spinlock_t comp_workspace_lock[BTRFS_COMPRESS_TYPES] - int comp_num_workspace[BTRFS_COMPRESS_TYPES] - atomic_t comp_alloc_workspace[BTRFS_COMPRESS_TYPES] - wait_queue_head_t comp_workspace_wait[BTRFS_COMPRESS_TYPES] BTW, while accessing one compress type of these variables, the next or before address is other compress types of it. So this patch puts these variables in a struct to make cache friendly.

This patch eliminates the last item of prop_handlers array which is used to check end of array and instead uses ARRAY_SIZE macro. Though this is a very tiny optimization, using ARRAY_SIZE macro is a good practice to iterate array.

This array is used to record attributes of each raid type, make it public, and many functions will benifit with this array. For example, num_tolerated_disk_barrier_failures(), we can avoid complex conditions in this function, and get raid attribute simply by accessing above array. It can also make code logic simple, reduce duplication code, and increase maintainability.

Just call kmem_cache_zalloc() instead of calling kmem_cache_alloc(). We're just initializing most fields to 0, false and NULL later on _anyway_, so to make the code mode readable and potentially gain a bit of performance (completely untested claim), we should fill our btrfs_trans_handle with zeros on allocation then just initialize those five remaining fields (not counting the list_heads) as normal.

Leandro Awa writes: "After switching to version 4.1.6, our parallelized and distributed workflows now fail consistently with errors of the form: T34: ./regex.c:39:22: error: config.h: No such file or directory From our 'git bisect' testing, the following commit appears to be the possible cause of the behavior we've been seeing: commit 766c4cbf" Al Viro says: "What happens is that 766c4cbf got the things subtly wrong. We used to treat d_is_negative() after lookup_fast() as "fall with ENOENT". That was wrong - checking ->d_flags outside of ->d_seq protection is unreliable and failing with hard error on what should've fallen back to non-RCU pathname resolution is a bug. Unfortunately, we'd pulled the test too far up and ran afoul of another kind of staleness. The dentry might have been absolutely stable from the RCU point of view (and we might be on UP, etc), but stale from the remote fs point of view. If ->d_revalidate() returns "it's actually stale", dentry gets thrown away and the original code wouldn't even have looked at its ->d_flags. What we need is to check ->d_flags where 766c4cbf does (prior to ->d_seq validation) but only use the result in cases where we do not discard this dentry outright" Reported-by: NLeandro Awa <lawa@nvidia.com> Link: https://bugzilla.kernel.org/show_bug.cgi?id=104911 Fixes: 766c4cbf ("namei: d_is_negative() should be checked...")
