* fs/ntfs3: Add sync flag to ntfs_sb_write_run and al_updateKonstantin Komarov2021-09-211-4/+4
| | | | | | | This allows to wait only when it's requested. It speeds up creation of hardlinks. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Use min/max macros instated of ternary operatorsKari Argillander2021-09-161-3/+3
| | | | | | | | | We can make code little bit more readable by using min/max macros. These were found with Coccinelle. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Use clamp/max macros instead of comparisonsKari Argillander2021-09-161-5/+3
| | | | | | | | | We can make code little more readable by using kernel macros clamp/max. This were found with kernel included Coccinelle minmax script. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Remove always false condition checkKari Argillander2021-09-161-4/+1
| | | | | | | | | We do not need this check as this is same thing as NTFS_MIN_MFT_ZONE > zlen. We already check NTFS_MIN_MFT_ZONE <= zlen and exit because is too big request. Remove it so code is cleaner. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Fix ntfs_look_for_free_space() does only report -ENOSPCKari Argillander2021-09-161-24/+27
| | | | | | | | | If ntfs_refresh_zone() returns error it will be changed to -ENOSPC. It is not right. Also caller of this functions also check other errors.

* fs/ntfs3: Rework file operationsKonstantin Komarov2021-08-311-52/+35
| | | | | | | | Rename now works "Add new name and remove old name". "Remove old name and add new name" may result in bad inode if we can't add new name and then can't restore (add) old name. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Restyle comments to better align with kernel-docKari Argillander2021-08-301-133/+111
| | | | | | | | | | | | | | | | | | Capitalize comments and end with period for better reading. Also function comments are now little more kernel-doc style. This way we can easily convert them to kernel-doc style if we want. Note that these are not yet complete with this style. Example function comments start with /* and in kernel-doc style they start /**. Use imperative mood in function descriptions. Change words like ntfs -> NTFS, linux -> Linux. Use "we" not "I" when commenting code. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Do not use driver own alloc wrappersKari Argillander2021-08-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem with these wrapper is that we cannot take off example GFP_NOFS flag. It is not recomended use those in all places. Also if we change one driver specific wrapper to kernel wrapper then it would look really weird. People should be most familiar with kernel wrappers so let's just use those ones. Driver specific alloc wrapper also confuse some static analyzing tools, good example is example kernels checkpatch tool. After we converter these to kernel specific then warnings is showed. Following Coccinelle script was used to automate changing. virtual patch @alloc depends on patch@ expression x; expression y; @@ ( - ntfs_malloc(x) + kmalloc(x, GFP_NOFS) | - ntfs_zalloc(x) + kzalloc(x, GFP_NOFS) | - ntfs_vmalloc(x) + kvmalloc(x, GFP_NOFS) | - ntfs_free(x) + kfree(x) | - ntfs_vfree(x) + kvfree(x) | - ntfs_memdup(x, y) + kmemdup(x, y, GFP_NOFS) ) Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Use kernel ALIGN macros over driver specificKari Argillander2021-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The static checkers (Smatch) were complaining because QuadAlign() was buggy. If you try to align something higher than UINT_MAX it got truncated to a u32. Smatch warning was: fs/ntfs3/attrib.c:383 attr_set_size_res() warn: was expecting a 64 bit value instead of '~7' So that this will not happen again we will change all these macros to kernel made ones. This can also help some other static analyzing tools to give us better warnings. Patch was generated with Coccinelle script and after that some style issue was hand fixed.
