Subject: [PATCH v4 00/13] add the latest exfat driver
Date: Thu, 21 Nov 2019 00:26:05 -0500 [thread overview]
Message-ID: <20191121052618.31117-1-namjae.jeon@samsung.com> (raw)
In-Reply-To: CGME20191121052913epcas1p1b28d2727dca5df42a6f2b8eb6b6dbcbb@epcas1p1.samsung.com
This adds the latest Samsung exfat driver to fs/exfat. This is an
implementation of the Microsoft exFAT specification. Previous versions
of this shipped with millions of Android phones, and a random previous
snaphot has been merged in drivers/staging/.
Compared to the sdfat driver shipped on the phones the following changes
have been made:
- the support for vfat has been removed as that is already supported
by fs/fat
- driver has been renamed to exfat
- the code has been refactored and clean up to fully integrate into
the upstream Linux version and follow the Linux coding style
- metadata operations like create, lookup and readdir have been further
optimized
- various major and minor bugs have been fixed
We plan to treat this version as the future upstream for the code base
once merged, and all new features and bug fixes will go upstream first.
v4:
- Declare ALLOC_FAT_CHAIN and ALLOC_NO_FAT_CHAIN macros.
- Rename labels with proper name.
- Remove blank lines.
- Remove pointer check for bh.
- Move ep into loop in exfat_load_bitmap().
- Replace READ/WRITE_ONCE() with test_and_clear_bit() and set_bit().
- Change exfat_allow_set_time return type with bool.
v3:
- fix wrong sbi->s_dirt set.
v2:
- Check the bitmap count up to the total clusters.
- Rename proper goto labels in several places.
- Change time mode type with enumeration.
- Directly return error instead of goto at first error check.
- Combine seq_printf calls into a single one.
